The “Titans” singer is PETA’s new spokesperson for Body By Vegan. In the ad campaign, she looks gorgeous while posing totally nude and biting a strawberry. Dawn’s vegan lifestyle was inspired by her father, who was diagnosed with Non-Hodgkin lymphoma. This caused her to do some research and better her health habits.

“My whole life has changed,” says Dawn, a self-described “avocado junkie.” “I get up earlier, I want to exercise, I feel better, my skin feels better—and these are things I didn’t even know [about vegan eating], coming from the south, coming from New Orleans.”
